The ability to display and inspect powder diffraction data quickly and efficiently is a central part of the data analysis process. Whilst many computer programs are capable of displaying powder data, their focus is typically on structure solution. The research proposes a lightweight powder diffraction visualization program with the capability of fast rendering to compare powder data sets. Based on the success of the earlier version and user requests, Jpowder has been extended to display powder diffraction datasets using stack plot, which options to use meta-data for crystallographic powder diffraction data in XML format. Such stack plots allows crystallographers to identify phase transitions in materials.
